3 Claims. Cl. 206-62) This invention has to do with photographic slidemagazines.

The major object of this invention is to provide a novel photographicslide magazine wherein the individual slides are retained in theirpockets or cells by a retainer that may be moved to inoperative positionwhen it is desired to insert or withdraw slides from the magazine.

A further object of the invention is to provide a novel structure formounting, locating and moving such a retainer.

These and other objects will be apparent from the drawings and thefollowing description. Referring to the drawings:

FIG. 1 is a plan view of a slide magazine according to a preferredembodiment of the invention;

FIG. 2 is a side elevational View of the magazine of FIG. 1;

FIGS. 3 and 4 are cross-sectional views on lines 3--3 and 4-4 of FIG. 2,respectively;

FIG. 5 is an enlarged fragmentary sectional view showing a slideretainer held in inactive position by the manual control member on themagazine.

FIG. 6 is an enlarged fragmentary sectional view of an inverted magazineas the same appears when in the projector adjacent the slide chute andthe slide retainer is moved to inactive position by means on theprojector.

The drawing shows a slide magazine M which is adapted to be used in anautomatic slide projector such as that disclosed and claimed in parentapplication Serial No. 723,623, filed March 20, 1958, for AutomaticSlide Projector, and of which the present application is a division.

Referring now to FIGS. 1-6, which illustrate a preferred form ofmagazine, this comprises an apertured bottom wall 70, corresponding sidewalls 71 and evenly spaced, laterally extending partitions 72 which formpockets for receiving the individual slides. The magazine also has endwalls 73 which are substantially rectangular.

On each side wall I provide a flexible slide retainer 75 which may bemade of metal and which runs the entire length of the magazine. Eachmember 75 has a side section 76 and an inwardly disposed scallopedflange 77. The side sections are supported, respectively, on a pair offiat, spring metal brackets 78 attached by rivets 80 or other means tothe side walls of the magazine. The brackets normally lie against thesides of the magazines in recesses 81. However, to insert or removeslides it is necessary to move the slide retainers outwardly as shown inFIGS. 5 and 6. This may be accomplished manually (FIGURE 5) by rotatinga rod 82 which has a central crank 83, the ends of the bar beingprovided with eccentric end portions 84 beneath the brackets 78. The rodis recessed into the side walls of the magazine.

FIGURE 6 illustrates automatic displacement of the 3,147,859 PatentedSept. 8, 1964 slide retainers. When the magazine is inserted into theprojector the slide retainers are cammed outwardly automatically whenthey engage fixed pins 86 (only one shown in FIGURE 6) on the projector.These pins also serve as an indexing means in conjunction with thescalloped edges a of the flanges 77 If desired the magazine may haveindicia on its bottom wall designating the numbers of the slide pocketstherein, for viewing when the magazine may be inverted during operation.

This automatic control of the slide retainers is further described andclaimed in said Serial No. 723,623 to which reference is made fornecessary further detail.

While I have shown and described a preferred form of my invention, Icontemplate that various changes and modifications can be made thereinwithout departing from the invention, the scope of which is indicated bythe following claims.

I claim:

1. A slide carrying tray comprising, in combination; an elongated trayhaving a rectangular cross-section, open at one side, and first andsecond walls interconnected by septums to hold slides in spaced relationfor movement from and to the tray through said one side by slidechanging means; slide retaining means extending longitudinally along andbeyond the edge of said first wall adjacent said open side having aprojecting lip for overlying slides to prevent removal thereof,resilient arm means comprising longitudinally spaced spring metal stripssecured at one end to the ends of said slide retaining means andextending tranversely across said first wall toward the opposite edgethereof, and means securing the other ends of said strips to said firstwall, said resilient arm means biasing said slide retaining means intoslide retaining position and permitting swinging movement thereoftogether with said lip away from said slide overlying position andwithdrawal of slides from the tray.

2. A photographic slide magazine adapted to be mounted for selectivedisplacement along a longitudinal guide path in a slide projector havingparallel side walls joined at opposite ends by parallel end walls and abottom wall, said magazine being open at its top for the receiption andwithdrawal of slides, lateral partitions parallel to the end wallsdividing the interior of said magazine into a plurality of individualslide receiving cells of generally rectangular cross section all open tosaid open top of the magazine, a slide retainer mounted externally onsaid magazine for swinging movement between a slide retaining positionat said open top where it overlies at least a part of each cell to blockthe slide therein against withdrawal from the magazine and an inactiveposition Where it is clear of said open top, and a manual operatingmember pivoted about an axis extending along the length of the containerand having operative motion transmitting connection with said slideretainer.
